In this study, the accuracy of the latest mean dynamic topography model (MDT), DTU22MDT, is determined based on data collected from 14 tide gauge stations along the coast of Vietnam, from the North to the South. The process of assessing the accuracy of the DTU22MDT model is carried out carefully and precisely, involving determining the model’s height at tide gauge stations, quality checks of the data, and evaluation of the model’s accuracy.

The paper studies the lipid and fatty acid composition of the sea cucumber Thelenota ananas collected on Bai Dong Island, Ha Long Bay, Vietnam. The total lipid content of dry sample weight was relatively high (11.89%). The triacylglycerol TG has the highest concentration in total lipids with a ratio of up to 66.73%; the PL and PI classes do not have a significant difference with the proportions of 13.44 and 11.65% in total lipids. Two classes of sterol ST, hydrocarbon-wax HW and free fatty acid FFA account for a small proportion.

The analysis results show that among coral samples belonging to the same species, the composition and content of fatty acids are similar; on the contrary, there are certain differences between samples of different species, which reinforces the hypothesis that the proportion and relative composition of FA in marine organisms are specific to each group and species. This study has yet to address the effects of environmental conditions, reproductive cycles, or food sources, and we hope to have the conditions to conduct such studies in the future.

This study proposes the application of Ensemble Decision Tree Boosted (EDT Boosted) model for forecasting the surface chloride concentration of marine concrete Cs. A database of 386 experimental results was collected from 17 different sources covering twelve variables was used to build and verify the predictive power of the EDT model.
